Question about IBM xSeries Computers & Internet

1 Answer

IBM xSeries 3550 M3. One fan has failed. While waiting for a replacement can I stop the server from shutting down automatically?

This server has ESX installed. After the fan failed the server will boot until ESX is up and then the server shuts down gracefully. We have ordered a replacement fan but I would like to run the server with only 5 fans until the replacement arrives. Is this possible?

    Hi Terence Grey, I want to help you with your problem, but I need more information from you.

    The servedr will shut down if you removed the fan. with one fan not running, but still installed in the system to ensure proper air flow it should run with the other fans speeding up to make up for the failed one.

    Did you remove the failed fan?

    We moved the failed fan to the no. 3 position that blows over the memory instead of the cpu and the server then continued to run with only 5 fans. Thank you for your comments.

Assuming that this is resolved as it appears to be an old, time-sensitive issue.

Although I would say that what you're asking would have been a design choice on IBM's part. The BMC would dictate fan curve and if one of the fans is not spinning at the minimal RPM - as specified in that fan curve - then it would obviously shut the system down to protect it from heat damage.

You may be able to adjust this using various commands in the BMC but I am not familiar with IBM's hardware. (Which is likely different in the same way that Dell's iDRAC differs from HP's iLO, etc.)

I'd say it's unlikely either way.

SOURCE: Install windows xp on a IBM xseries 200 8479 computer

You have to download the scsi driver from the ibm site. You'll need a floppy and floppy drive. When you boot with your xp cd to setup press F6 to install driver.

Link to your IBM. Since IBM have different models you have to type it at the provided link.

good luck

SOURCE: server doesnt boot

First create a floppy disk with your RAID driver for W2K3 Server. Next boot the server with the W2K3 Server CD, and hit F6 when prompted, and S to add the specific driver for your RAID and using the floppy to get the driver installed.

Next boot to the recovery console of W2K3 Server. If it finds your hard disk, it will even ask for your Administrator's Password to continue. If this works, then you are probably home free.

Get to the command line of the W2K3 Server Repair console and perform some directory searches to see if the data is there and intact. You can also perform a CHKDSK from that console.

Once you have made sure your data is there and intact, type these two commands: FIXMBR and FIXBOOT

This should solve the problem and when you EXIT out of the console, it should reboot. Remove the CD and it "should" re-boot from the hard disk.

If you still have problems, let me know with how far you got with the steps above. I have another solution but need to know your RAID controller's model (ServeRAID 5i, 6i, etc).

Those beeps mean that your RAM is not functioning. Are you sure you got the right upgrade type. Sometimes it'll fit into socket but won't work because of speed. Or just try reseating the modules.

I have an IBM x346 eserver that has run well for years. The fans are now very load (whirling noise). I typically only hear this noise when the room temp is high, but this server is in a cool room with no...

It sound like the CPU fan or server case fan/s or power supply fan bearings are worn.
To determine which fan/s is faulty open the computer case and stop each fan from spinning, one at a time to determine the noisy fan. Once you have identified the noisy fan then replace that fan.

Sir, my xseries 226 server he is power on but 1 or 2 second sysetm all power lite & fan start after 1 or 2 second stop all lite & power

Hi, Welcome to fixya
Please re fix the server ram modules and unplug all pci cards . Now power on the server . If it works remove the complaint pci card .
If you find same issue again then this should be a power cage problem. If server didn't get enough power from the power supply it will stop suddenly when power on server . Your complaint seems to be the same . Replacing the power cage will fix the issue

The fan light indicates a problem in xseries 346 and the fan rate is very high )there is high noise from the fans. what can be the problem?

There are many fans in servers. If one dies the others will work overtime to keep it cool. It sounds like you lost a fan somewhere.

When the server starts up you may see a POST message on the screen pointing out which fan failed. Otherwise, remove the cover and look for a failed fan. Be careful not to leave the cover off for very long. The cover is what makes sure the air flows correctly over the components.

If this helps please vote for my solution.

I have an IBM eserver x series 255 and i just replaced the scsi drive on it but i still see the drive in failed status i want to know where in the bios do i go to configure the new drive?

If this drive is hot swappable, and it's a part of a RAID array, the RAID controller should handle the rebuild of the drive automatically. There are two easy ways to configure the new drive. 1 - reboot the server, wait for the ServerRAID BIOS to start, then press Ctrl + I (or whatever it says) to enter the mini configuration wizard. Once you're in there, you can view and configure the drive as needed. If you installed the replacement drive, and the status light of the new drive is blinking orange/amber, it probably means that the controller has begun rebuilding the array and you just have to wait. Depending on the size of the drive, and the amount of data, and the speed of your controller, rebuilding of a failed drive can take hours.
